OK, I was holding off including these little fellas, as they are superstars in their own right already and we were respecting their privacy as celebrities. It is tough for these guys to just blend in with the crowds anymore and the simplest of tasks such as taking the kids out often ends in a frenzy of paparazzi. But due to popular demand I have to include them.There are 28 different types of clown fish, the largest being about 18cm (7″). The clown fish forms a symbiotic relationship with its host anemone and will defend its home with vigour. Spawning season lasts all year. The female lays their eggs next to the host anemone, which they then are guarded by both parents. The eggs take 7 days to hatch and hatch about an hour after sunset to avoid predators.Now how does the clown find find his way home? Research at JCU suggests that the anemone fish smells the scent of the host anemone. When the baby clown fish are ready to move out and find a place of their own they use this scent to locate a suitable anemone.
